Question

Write a C++ programs to:
1. Create a class called Student with four (4) private member variables, name (string), quiz, midterm, final (all
double type);
2. Include all necessary member functions for this class (at least 1 constructor, 1 get function, and 1 grading
function – see #6);
3. Declare three (3) objects of Student type (individual or array);
4. Read from the keyboard three (3) sets of values of name, quiz, midterm, final and assign them to each object;
5. Using the object’s member function to calculate the grade for each student (grade = quiz * 0.2 + midterm * 0.4 +
final * 0.4)
6. Display on the screen only the name of each student and the grade.

Answer 1

#include <iostream>

using namespace std;

class student
{
   
    private:
    string name;
    double final, quiz, midterm,grade ;
   
   
    public:
    student();
    void getdata();
    void grading();
  
};

    student :: student()
{
cout<<"This is Student Details"<<endl;
}
void student :: getdata()
{
cout<<"Enter the student Name"<<endl;
cin>>name;
cout<<"Enter the student midterm marks"<<endl;
cin>>midterm;
cout<<"Enter the student quiz marks"<<endl;
cin>>quiz;
cout<<"Enter the student final marks"<<endl;
cin>>final;

grade = (quiz * 0.2 + midterm * 0.4 +final * 0.4);

}

void student :: grading()
{
cout<<"Student Name :"<<name<<endl;
cout<<"Student grade:"<<grade<<endl;

}

int main()
{

student s;
s.getdata();
s.grading();

return 0;
}
